Patented Dec. 9, 1941 UNITED STATES PATENT F FICE MARKING MACHINE George Stiegler, Cincinnati, Ohio Application June 30, 1939, Serial No. 282,241

(01. Hit-316) 4 Claims.

My invention relates to machines designed particularly for marking articles in laundries or marking goods with style and lot numbers, and many other uses which will be apparent. It is an improvement on my marking machines disclosed and claimed in my prior Patents Nos. 1,891,656 issued December 20, 1932, and 1,993,461 issued March 5, 1935, wherein machines of this character are provided with power means for operating the marking mechanism, and means for tripping the power means to instantly release the marker after each impression.

The object of my present improvement is to arrange my marking machines as shown in my previous patents, in a frame with power means for operating the marking and inking mechanisms.

A further object is to pivot the marking device in the frame for ready access in changing the relative positions of the dials.

A further object is to provide a trip for instant return of the marking device after each impression.

My invention will be further readily understood from the following description and claims, and from the drawings, in which latter:

Fig. 1 is a front elevation of my machine.

Fig. 2 is a side view of the same, partly in section.

Fig. 3 is a vertical section of a portion of the machine, taken in the plane of the line 33 of Fi 2.

Fig. 4 is a detail section, taken in the plane of the line 4-4 of Fig. 3, and;

Fig. 5 is a horizontal section, taken in the plane of the line 55 of Fig. 3.

The marking mechanism and inking mechanism I2 is mounted in a U-frame l3 being of a construction as shown in Patent No. 1,993,461, issued to me March 5, 1935. The handle M of this marker is provided with a rabbet l5 which engages in a U-flange l8 secured to slide bars H.

I prefer to mount the marking mechanism in a frame l8 secured to a pedestal H! which may be of a height suitable for bench or floor mounting. The marking device frame I 3 is pivoted in the frame l8, as by being mounted on studs 28 extending through the frame l8 and threaded into the U-frame l3. A pull pin 2| locks the marker in operative position. When it is desired to rearrange the marking dials the pull pin is withdrawn and the marker tipped backward for visual arrangement of the dials.

The bars l1 are arranged to slide in the frame |8, being guided by guides 25 and 26 secured to the frame. A plate 21 is securedbetween the bars l1 and moves with the bars. A plate 28 is slidable between the plate 21 and guides 29. A gear rack 30 is secured to the plate 28. An arm 3| pivoted on the plate 28 has a pawl 32 arranged to engage a notch 33 in the plate 21. A spring 34 secured to the plate 28 normally maintains the pawl in engagement with the plate 21 and has suflicient tension to maintain the plates as a unit during the stamping operation.

A shaft is journalled in the frame l8 and has a segment gear 4| secured thereto and arranged to engage the rack 38.

I have shown hydraulic means for operating the segment gear 4|, although suitable other means may be employed, such as a foot or hand lever.

Most laundries have air pressure lines and therefore I have shown a control valve 42 having a movable valve core 43 controlled by a push pin 44 positioned near the front of the machine for controlling the flow of air from the line 45 to either end of a cylinder 49, through the connections 41 and 48. A piston in the cylinder is connected to a gear rack 5| slidable in a guide 52 on th frame. A gear 53 secured to the shaft 40 meshes with the rack 5|.

With the machine in the position shown in the drawings, the operator holds the material to be marked on the pad 54 below the marking device. Pressing down on the push pin 44 causes the valve to open the line 48 to the line 45 for moving the piston 58 endwise in the cylinder 49. Thus rotating the gear 53 and the segment 4| causing the plates 21 and 28 to be lowered, pulling the bars l1 therewith and moving the marker to marker position. When the marker contacts the pad 54 it will arrest further movement of the plate 21 and the pawl 32 will slide over the plate. As soon as this disengagement takes place, springs 55 attached at their upper ends to the frame I8 and at their lower ends to the bars l1, will draw the bars I1, plate 21 and the markin device upward. Thus a fast instant stamping and return takes place. Release of the push pin 44 will cause air to flow from the pipe 45 through 41 to return the piston to normal position. Suitable bleeder openings in the valve as indicated at 56 and 51 prevent locking of the cylinder,

A pin 58 limits the upward movement of the bars l1 and a lug 59 extending from the plate 21 limits the upward position of the plate 28 relative to the plate 21.

Having thus fully described my invention, What I claim as new and desire to secure by Letters Patent, is:

1. In a marking machine having a reciprocating marker, a pair of members, positive means for moving one of said members, said other member connected to said marker, releasable means between said members for instant return of the said marker after each impression, and means for retracting said second-named member.

2. In a marking machine having a reciprocating marker, a slidable plate connected to said marker, a second plate adjacent to said first named plate, a rack on said second-named plate, a gear engaging said rack, means for rotating said gear, a pawl pivoted in said second-named plate engaging said first-named plate and held in engagement by tension means, and tension means for instantly retracting said first-named plate upon disengagement of said pawl.

V 3. In a'marking machine having a reciprocating marker, a pair of plates, one of said plates connected to said marker, a pawl pivoted in the other plate engaging said first-named plate and held in engagement by tension means, said second-named plate provided with a rack, a segment gear engaging said rack, means for rotating said segment gear to move said plates downward, and tension means for instantly retracting said first-named plate upon release of said pawl.

4. In a marking machine having a reciprocating marker, a pair of plates, one of said plates operating said marker, the other plate having connection with reciprocating means, a pawl on said second-named plate engaging said firstnamed plate permitting disengagement of said plates upon stoppage of said first-named plate,

tension means for normally maintaining said pawl in engagement, and tension means for lnstantly returning said first named plate upon disengagement of said pawl. n I 7 GEORGE S'IfIEGLER;
